I recently went vegan for veganuary as my partner has been vegan/vegetarian her whole life. It's definitely stuck, and I am now completely plant based. I was being a flexitarian beforehand only eating meat and dairy when I wasn't with her. A weekend vegan if you wish.
Have had more energy, better sleep, more mental clarity, more "regular" digestive system, and I'm happier. Having read through this whole thread it makes me laugh that 12 months ago I was anti vegan seeing it as restricting and "where do you get your protein though" yet here I am, a leaner, healthier, less sluggish person! It was actually a really easy switch.
Epic mature grated cheese is amazing, and 99% of birdseye green cuisine is too. We mainly cook from scratch now and limit I've tried so many different foods that I never thought I would, plantains for example.
Easiest way to have a decent vegan meal? Get all your veg, chop it up, chuck in the oven with a sprinkle of salt and pepper, rosemary, and a bit of oil. Absolutely amazing.
Also, only draw backs is the b12 deficiency and lack of decent chocolate. A supplement and a vego bar solves both though
